The launch of the blockbuster digitally organized 3d film; Avatar has taken a huge step to improvement for many film makers. People are now craving for more 3d films that would take them to a new level of 3d viewing experience using the 3d glasses. Now technology has even made it more convenient with the release of new inventions like the 3d DVD players and televisions in 3d format. The 3d world has made its way to success with the advancement of technology these days. Theaters are typically known to hand in 3d glasses to the audiences. But now glasses are available on your local retail store which are usually distributed by companies that produces 3d compatible home entertainment systems. Many manufacturers include these glasses as a kit or for free if you buy any of the 3d compatible appliances. Some of the 3d glasses included can operate through infrared.
Three dimensional glasses is not a new way us because they have been around for many centuries since the making of 3d films. It was already used when the first 3d movie was released decades ago. However during those times, these films were not very popular and the technology was not yet developed. This is the reason why people failed to take interest on such films and device like 3d glasses. Disney characters before can be viewed using View Masters, twenty years ago. The idea of the View Master was to take its viewers into the depth of illusion and trick their perception of 3d images. The method involves two pictures of the same image which are slightly angled. Even though the images are the same, with the use of 3d glasses our eyes will not be confused because we are seeing it in two different angles. The perceived images will be then correlated by the brain where three dimensional image will be created.
3d movies are employing the same concept as the old format though you are not seeing two pictures on the screen. Film makers use anaglyphic images which are made up of two pictures greatly imposed to each other and for the benefit of each of our eyes they are angled slightly. 3d glasses are important as these images cannot be seen clearly with our naked eyes. These glasses will filter the images so that only one image will enter into one side of the glasses. There are different types of glasses available in the market today. One of them is the polarized 3d glasses where each of the lenses used is polarized in a different way. These lenses will accept only one image that is projected by the polarized video on the screen. The other type of glasses that uses red and blue lens filter works the same way the only difference is that it uses red and blue lens and anaglyphic video to present the images. There are other types of glasses that use new technology like the passive and active 3d glasses that works with different specifications.
